The news listed that the average price of a gallon of
gasoline in the city is $3.20 with a +5% margin of error. if
this correct what two dollar values the average cost of a
gallon of gasoline should be between?

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

answer: list the statements and i will follow up!

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

i think the answer is b x = 1, y = 35/2
